Netflix, whose shares rose 8% in extended trading, has been hugely successful in attracting more subscribers through the popularity of its original shows. Netflix, whose original shows include Narcos and Stranger Things, said on Wednesday it signed up 5.12 million subscribers outside the United States in the quarter ended Dec. 31. Analysts on average had estimated 3.73 million additions, according to research firm FactSet StreetAccount.

In the United States, Netflix added 1.93 million subscribers, compared with the average estimate of 1.44 million. The company plans to spend $6 billion in original content in 2017, a $1 billion increase from last year. Netflix – whose competitors include Amazon.com’s streaming service and Hulu, besides cable channels such as HBO – plans to release over 1,000 hours of original programming this year, up from 600 hours last year.
